I have a two door car and was thinking bout getting rid of it and getting a 4 door suv instead bc i thought it wasn;t legal but a friend told me it is???
Yes it's legal! If you can fit the car seat in safely in the back seat then there is no reason to need an SUV. I have a VW Beetle and I have 2 kids, one in a booster and one that has been in a rear-facing infant seat, and a rear-and front-facing secondary seat. It is legal and safe, as long as they are buckled in correctly.
I have a 2 door sunfire, and I have had my son's car seat in the car since he was born. It is not illegal, but it is inconvenient. I wish I had 4 doors.
